Distributions of Carbon Nitrogen and Phosphorus in the Products from SCWG of Cyanobacteria

Abstract:

The cyanobacteria, salvaged from TaiHu Lake every year, contain high water content and organic matters. Nowadays the problem how to deal with such cyanobacteria has attracted wide attention. In this study, the SCWG is applied to the safety disposal and resource utilization of cyanobaceria to reveal the distributions and forms of carbon, nitrogen and phosphorus in the supercritical products under different reaction conditions. The study results show that SCWG is a good way for the disposal and utilization of cyanobaceria. After SCWG, the C of cyanobaceria exists mainly in the solid residue in the form of coke and heavy oils.High temperature and prolonging reaction time lead to C transfers from s/l phase to gas phase. While N of cyanobaceria is found in liquid phase in the form of NH₃-N, and more than 90% of P can be found in the solid residue.
